How about toy fire trucks, dump trucks and recycling trucks, even? The Oakland Public Library has all those and more, available for check-out at a growing number of branches.

They are all part of the toy lending library, now in its second year with no end in sight. The library has exhausted the Pacific Library Partnership Innovations & Technology Grant provided in 2014 to establish one of only a very few public library toy programs in the country, but the program’s success has led to its now being included in the library’s collection budget.

After the toy lending library debuted at four branches in a 2015-16 fiscal year pilot program, this year the library added two more and plans to do the same next fiscal year.

Someday, the hope is, all 17 branches will have toys for check-out. But every branch has some toys that are kept at the library that visitors can play with while there.

The entire circulating collection, which can be perused online at http://oaklandlibrary.org/kids/welcome-parents/toy-lending-library, also can be accessed at any branch simply by putting a hold on the toy and having the library deliver it there.

The six with toy libraries already in place are: the Main Branch, West Oakland, Chavez, Elmhurst and, as of this year, Melrose and Rockridge.

The next two branches have not been decided, but the library wants equal geographical distribution throughout the city, said Nina Lindsay, supervising librarian for programs, in an interview.

Toys are typically loaned out in mesh, bar-coded bags that reside behind the reference desk.

“Our libraries and systems are set up for things that are book-shaped, or DVD-shaped. A drawstring mesh bag full of plastic dinosaurs does not stack as nicely as a book, so we just needed to test run a sample set,” Lindsay said of the process of developing the toy library system.

Each of the six libraries has about 30 toys to choose from. There are dolls of varied ethnicity, hats — everything from motorcycle helmets to construction hardhats, or headgear resembling that worn by bus drivers, airplane pilots, astronauts, firefighters, police, postal workers and others — cars, plastic farm animal sets, draw-and-erase boards, balls and music-makers.

Some are of a more scientific bent, including doctor kits and a collection of magnifying glasses, prisms and binoculars. The age range is set at infant to 6 years old.

“Helen Bloch, manager for the children’s room at the Main Library, had the inspiration for this collection after seeing one at Middle Country Library in New York, while on vacation five years ago,” Lindsay wrote in an email.

“When I saw the posting for the Pacific Library Partnership’s Technology and Innovation grant, I saw an opening,” she wrote

Lindsay said that other than a toy library in Salinas and a large one in Cuyahoga, Ohio, when she was in the process of starting the program, she was unable to find many other examples of toy libraries in the country, although social service organization and hospitals have a history of them.

“We found little other evidence of public library toy collections when we proposed our grant, though more libraries are now experimenting with lending non-traditional items,” she wrote.

Locally, the Habitot Children’s Museum in Berkeley was helpful, for instance, in deciding what sanitizing product to use to clean returned toys before they are put back on the shelves, she said. The library was careful to find a non-toxic, non-allergenic product, Benefect, she said.

Toys can be borrowed for three weeks at a time, but no late fees are assessed. Otherwise, lending policies are the same as the rest of the libraries’ offerings: Up to three renewals are allowed unless another client’s put a hold on something.

Toys with multiple parts were selected in part based on their ability to survive the occasional loss of a piece, Lindsay said.

The library does not accept donated toys, instead recommending they be taken to Goodwill, Salvation Army, Bananas on Claremont Street or donated them to the annual Oakland Museum White Elephant sale, she said.

In the case of new, wrapped toys, the library suggests giving them to the Oakland mayor’s December toy drive or to UCSF Benioff Children’s Hospital Oakland.

“We’re not accepting donations because we have very specific criteria for what we need, and what we can feasibly circulate. Managing donations can require high capacity, and we know there is need to get toys directly into the community, so we recommend a more expedient path for donors,” Lindsay wrote.

In the first year of the program, the toys were checked out an average of 3.89 times, while picture books circulated 3.09 times, on average, a survey found.

Besides spending $13,000 to buy toys and bags, the pilot program required $2,000 for display furniture, $1,000 for promotional materials and $200 for sanitizing supplies, along with staff time for planning, design testing and outreach.

The giant dinosaur toys, generally a foot or so long or tall — doll-size, Lindsay said — have been the most popular items so far. The least popular item? Those hats.
